Abstract (en)
It is determined whether each block (51) including a plurality of pixels extracted from a basic field (30) has an edge or not. Each of the pixels forming the block (51) having an edge is then analysed to determine whether it is stationary or non-stationary. An absolute value of a difference is then calculated between a pixel determined to be non-stationary and a pixel (91 or 92) in each pixel position or pixel positions (82 to 85) in a reference field (40) adjacent to the non-stationary pixel, and a correlation is found between such pixels in consideration of the calculated difference absolute-value. A motion vector is determined by the block matching method according to results of the determination, and allocated to each of the pixels. Thus, the motion vector of each block is corrected to an accuracy of each of the pixels. <IMAGE>
